What do these questions mean?? relations part two only btw

I'll do problem 1 to get you started.

1a. Pick any four ordered pairs of the form (x,y) such that y = 2x. In other words, these points are all on the line y = 2x.

Four such points are: (1,2), (2,4), (3,6) and (4,8)

There are infinitely many points to pick from.

1b. Similar to the first problem, but now y = x+5. Whatever the x coordinate is, we add 5 to it to get the y coordinate.

Four such points are: (0,5), (1,6), (2,7), (3,8)

There are infinitely many points

1c. Similar idea as before, but now y = x-4

Four points on this line are: (0,-4), (1,-3), (2,-2), (3,-1)

There are infinitely many points.

1d. Take half of the x coordinate to get the y coordinate. The equation is y = x/2 or y = (1/2)x or y = 0.5x

Four points on this line are: (2,1), (4,2), (6,3), (8,4)

There are infinitely many points.

all of the other ones have a specific pattern
